SECIEICATION forming part of Letters Patent No. 782,281, dated February 14, 1905.

Application filed Julie 9,1904. Serial No. 211,771.

l l i nmrr JouNsoN, citizens of the United States, residing at Sumner, county of Dawson, State of Nebraska, have invented certain new and useful improvements in Listed-(lern Cultivators, of which the following' is a specilication,

reference being' had therein to the accompanying drawings, in which- Figure 1 is a perspective view of the cultivator, the trough-shaped fenders being' removed; Fig'. Q, a side elevation thereof, showing' the trough-shaped fenders; Fig'. 3, a plan view; Fig'. sl. a 'front elevation, and Fig. 5 a detail plan view of the bearing-bar and the bearing-sleeves.

Listed corn is planted in a furrow havinga ridge on either side, and it has been heretofore dil'iicult to cultivate the corn during the early stages of its growth to keep it free from weeds. One of the great troubles was that the young' plants were destroyed and covered with earth by the cultivating` means.

lt is one of the main objects of this invention to provide a cultivator by which the `ground will be broken and the weeds destroyed and which at the same time will protect the young' plants and prevent them from being' injured or covered with earth.

Another object of the invention is to provide a cultivator adapted for use on sidehills, special means being' provided to keep the cultivator in line with the rows.

As shown in the drawings, the machine is designed to cultivate two rows of corn; but it is of course obvious that it may be arranged to cultivate one row or by adding' additional devices to cultivate more than two rows. lt is preferred, however, to construct it in the Yform shown.

Referring' to the various parts by numerals, l designates the transporting-disks,which are mounted in the lower ends of the supporting'- standards L). Four of these disks are provided, arranged axia'lly in line with each other and so spaced apart as to travel one on each side of each row of corn to be cultivated, as shown clearly in Fig'. 3.

To the upper end of each simporting-standard Q is rigidly secured a plate 3, said plates l stand ards.

being' secured to the outer sides of the outer standards and to the inner sides of the inner Each of these plates is formed at its upper end with an outward-extemling horizontal llang'e if. which carries the clamp 5. Rig-idly secured to the plates of each pair of standards by means of the clamps 5 is a horizontal bearing-sleeve 6, said sleeve serving' to rigidly connect together each pair of standards. These bearing-sleeves are loosely mounted on a transverse bearing-bar G", which is rigidly supported midway its ends, as will be hereinafter set forth.

Rigidly secured on each plate 3 is a rearwardextending' cultivator-beam T, those connected to the two outer standards inclining' outward and those connected to the plates of the inner standard inclining' inward and toward the longitudinal center line of the machine. to the inner sides of the cultivator-beams, near the rea'r ends thereof,are holders 8,said holders being' pivoted at their rear ends, as at in Fig'. 1, and adjustably connected at their forward ends, as at ll) in Fig'. l, so that their downward and forward inclination with respect to the cultivatorlbeams may be varied as desired. Extending downward and forward from each of these holders 8 and vertically adjustably connected thereto is a bar ll, a bolt l2 being' provided to hohl it in its adjusted positions. Secured to the lower end of each of these bars isa small shovel orcultivator-tooth 13. It will thus be seen that by varying' the adjustment atll) and by raising' or lowering' the bar ll the desired inclination and the proper height of the cultivator-tooth is secured. To the outer side of each beam is secured the rearward and outward extending' arm 11, which curves downward at its rear end and carries a large cultivator-shovel 15. This shovel may be vertically adjusted by means of the bolt 16.

The smaller shovels 13 of each pair of cultivater-beams are desig'ned to work on the inner sides of the ridges to destroy the weeds and break up the dirt, while the large shovels of each pair of beams are separated sul'liciently to bring' them in position to work near the tops of the ridges and are designed to work deeper in the soil than the shovel 13 to thoroughly break up the ground and to practically level Secured IOO the ridges. To prevent the dirt thrown up by l reach-bar for a purpose which will be hereinthe smaller shovels 13 from falling on the plants, trough-shaped fenders 33 are provided. which completely cover the plants between the two shovels. These fenders are connected at their forward ends to the su pporting-standards 2 by means of strap-irons 39 and to the bar 27 by means of chains 40.

At the inner side of each cultivator-beam is secured a rearward-extending bar 17,which carries at its rear end downward and inward inclined parallel bars or teeth, which form shields or dirt-checks 13. By describing these teeth as being inwardly inclined it will of course be understood that the bars of each pair of dirt-checks incline toward each other or toward the plants between them.

ating of the machine a row of plants is between each pair of cultivator-beams. The dirtchecks are arranged on the inner side of Iand slightly in the rear of the large cultivatorshovels 15, so as to prevent the earth turned up by said shovels from falling too far inward toward the plants. The bars of these dirtchecks will also act as breakers and will materially aid in pulverizing the soil. It is obvious that earth will pass between the bars of the dirt-checks in a finely-divided condition, leaving' the surface of the ground comparatively level and in a very loose condition.

An upward and rearward extending reachy bar 19 is rigidly secured near its forward end to the transverse connecting-bars 6, midway the ends of said bar. The rear end of this reach is curved downward and carries the downward-extending yoke 20, whose upper end is connected by a horizontal pivot to the reach, said pivot extendinglongitudinally of the machine in order thatthe yoke may swing from side to side of the machine. This yoke is provided at its lower end with the downward and rearward inclined arm 21, on the lower end of which is `journaled the transporting and guiding wheel 22, said wheel being at the longitudinal center of the machine and slightly in the rear of the large cultivatorshovels 15. The object of mounting this transporting-wheel on a laterally-swinging yoke is to permit it to swing to either side of the longitudinal center of the machine to adjust itself to a vertical position when the machine is used on sidehills. The advantage of this is obvious, as it acts as a brace or prop to maintain 'the rear end of the machine in line with the furrows and prevents it working gradually downhill, as would be the tendency if such a brace or prop were not provided. This wheel 22 also acts as a caster-wheel when turning the machine. The reach-bar 19 extends forward from the bearing-bar 6 horizontally and carries at its forward end the draft-bar 34, said bar being adjustably supported on the reach-bar by means of a hanger 34 to permit said draft-bar to be adjusted laterally on the It will of course be understood that during the operl after described.

Extending transversely of the machine and secured rigidly to the reach-bar slightly in the rear of the bearing-bar 61 is an angle-iron crossbar 24. To this latter bar are secured frames 25, one of which is located midway between each pair of cultivator-beams. These frames incline upward and slightly forward, their upper ends being connected by downward and forward extending rods 26 to the reach-bar 19.

Secured rigidly to the upper sides of each pair of eultivator-beams is a horizontal transverse bar 27, said bar serving to space the beams a suitable distance apart. Mounted on the upper side of each bar 27 is a short shaft 28. on the outer end of which is provided crank-arm 29. Connecting the free end of this crank-arm with the top of the frame 25 is a chain 30, said chain being detachably connected to said frameby means of a suitable hook device 31. On the inner end of each shaft 23 is rigidly secured a rearward-extending lever-32, and on the bars 27 adjacent each lever is a segment-rack 33, each lever being provided with suitable devices for engaging said rack to hold the lever in its adjusted position. l hen the rear ends of the levers 32 are forced downward, the strain is brought on the chains 30, which are connected to the upper ends of the frames 25. As these frames are rigidly connected by the rods 26 to the reach-bar 19 forward of the bearing-bar 6, it is obvious that said frames cannot be drawn rearward. As the cultivator-beams are loosely mounted on the cylindrical bearing-bar 6 by means of the sleeves 6, the rear ends of said bars are free to swing upward. The result, therefore, of forcing downward the rear ends of .the levers 32 will be to swing the cultivator-beams upward at their rear ends, said beams turning on the sleeves 6E. This upward movement of the beams will cause a slight rearward movement of the lower ends ofthe standards 2, the draft-bar 34 moving rearward on the reach-bar to accommodate itself to the movement of the standards. By swinging the levers 32 upward and forward the cultivatorbeams will be permitted to drop at their rear ends, as is obvious. By this means the cultivator devices may be lifted clear of the ground in order that the machine may be moved readily on its transporting-wheels. It `will also be understood that by means of the detachable connection between the chain 30 and the hook 31 said chain maybe varied in length as desired to secure the proper adjustment of the parts' and to permit the cultivatorshovels to work at the desired depth. As shown in Fig. 2 the cultivator-shovels are lifted above the ground out of operative position.

On each end of the draft-bar is mounted a draft-evener which consists of a bar 35, pivoted midway its ends in straps carried by the IOO IlO

draft-bar, the outer ends of said bar being connected by rods 36 to the supporting-standards Pivoted on the reach-bar forward of the bearing-bar 6 is a guiding-lever 3T, whose i forward end is connected by a link 3T tothe hanger 3 of the draft-bar. The rear end of this lever is in a convenient position to be manipulated by the driver to swing the draftbar toward either side of the longitudinal center of the machine. Secured to the transverse bar *A is a suitable keeper 24C, in the notches of which the guiding-lever may be placed to retain the draft-bar in the desired position. To the draftbar is secured the draft device with which the draft-animals are connected. VIt will therefore be seen that by shifting the draft-bar to one or the otherside of the longitudinal center of the machine the center of the pull on the machine will be shifted and any tendency of the machine to work laterally-- for instance, on sidehills-may be counteracted.

The bearing-sleeves 6 are looselysupported on the bearing-bar 6 in order that the disks and the cultivator-sleeve may follow automatically the furrows in which the corn is planted. This is a very desirable feature, as the distance between the rows of plants in listed corn varies, and it is important that the f 'transporting-wheels,a pairofcultivator-beams rigidlymounted at their forward ends and divergmg rearwardly, a small cultivator-shovel carried by each of said beams, said small shovels being arranged close together, a large l cultivator-shovel carried by each ofsaid beams in the rear of the small shovels, these large shovels being' arranged a greater distance apart than the smaller shovels, a dirt-check mounted adjacent each of the large shovels, and means for vertically adjusting the cultivater-beams.
